Title: Toy road graders
IPC: A63H17/12
Filed: 1973-01-11
Abstract: 1360765 Toy road surface scraper vehicles TONKA CORP 11 Jan 1973 [25 Feb 1972] 1607/73 Heading A6S A toy road surface scraper wheeled vehicle has a scraper blade 40, Fig. 2, which can be moved from a raised position to a lowered position, Fig. 3, where it engages the ground surface G to move sand, &c., as the vehicle is pushed over the surface, springs 37 biassing the blade to its raised position so as to avoid accidental damage to floors, &c. A scraper blade support plate 22 is journalled at one end about the front axle 18 of the vehicle, and is connected by a pair of pivoted links 34 to a handle 28 of inverted U-shape pivoted in the front body portion 19 of the vehicle. The springs 37 act in tension between a bracket 36 fast with the vehicle body and the handle 28, tending to turn the handle anti-clockwise about its pivot and thus raise the scraper blade 40 from the lowered position of Fig. 3 to the raised position of Fig. 2, in use, a single hand upon the handle 28 serves both to lower the scraper blade towards the ground G and also to push the vehicle along. The scraper blade 40 is pivoted by a central rivet 44 to the support plate 22 and has a rearwardly extending fork 45 with arms receiving the end 48 of a blade angle control hand lever 47. A spring 49 biasses the hand lever 47 downwards to engage in one or other of several angle locating notches 51 at the edge of the blade support plate 21. To adjust the angle of the scraper blade 40 on the vehicle, the hand lever 47 is raised against the biass of the spring 49 and thereby disengaged from a locating notch 51: it is then twisted, so that its end 48 turns the scraper blade 40 about its rivet 44: and then lowered, to engage with another locating notch 51. The toy vehicle includes a simulated power unit 11 at the rear pivoted by a bolt assembly 15 to a front unit 14 carrying the scraper blade 40, &c.
Patent GB-621188-A (GB)
Title: Improvements in or relating to the manufacture of aqueous emulsions
IPC: C09K23/00
Filed: 1947-01-17
Abstract: Stable aqueous emulsions or dispersions of long chain aliphatic substances, e.g. oils, fats and waxes, are prepared without frothing by employing as the emulsifying agent a minor proportion of a water-soluble methyl ether of a cellulosic compound and a major proportion of a water-soluble alkali metal salt of carboxy methyl cellulose.  The methyl ether, e.g. methyl cellulose, methyl ethyl cellulose and methyl hydroxy ethyl cellulose is employed in a concentration insufficient of itself to effect emulsification and the salt of carboxy-methyl cellulose has higher viscosity characteristics than the methyl ether.  Examples are given of the emulsification or dispersion of cod liver oil, cotton seed oil, a mineral oil and tallow.  In the case of tallow, the molten tallow at 40 DEG  C. is dispersed in an aqueous solution of the emulsifying agent at the same temperature and the dispersion is subsequently cooled.

Title: Improvements in or relating to pressure control systems for apparatus for sterilizing and similarly treating food products and the like by heat
IPC: A23L3/10
Filed: 1924-01-21
Abstract: 229,067. Ingram, H. Jan. 21, 1924. Electrically-actuated valves.-Fluid controlling valves 20, 21, used in apparatus for sterilizing and similarly treating food in vessels of the type described in Specification 218,426, [Class 49, Food &c.], having a tank containing water heated by steam coils &c. and provided with means controlled by the pressure and temperature in the tank for maintaining a pressure therein sufficiently in excess of that produced in the vessels to prevent their covers from being blown off, are controlled by means of Bourdon tubes or like pressure gauge devices controlling indicating hands which likewise serve as switches controlling electromagnets which operate the valves to admit fluid to the tank 10 from a pressure reservoir, or to allow it to exhaust into the air as required. The. tank 10 contains a coil 11 through which steam or cold water can be passed and an annular or like tube 28 containing liquid, the quantity of which can be adjusted by means of a filling funnel 33 and a drain cock 31, and communicating by a pipe 35 with a Bourdon tube in a casing 39 giving motion through gearing of ordinary type to a hand 42, Fig. 4. A tube 9 leads from the tank 10 to a Bourdon tube giving motion to a hand 43 mounted on a sleeve on the spindle of the hand 42. The hands 42, 43 move over a dial carrying insulated metal strips 67, 68, 69. 70. The ends 86<1>, 89, 93, 96 of the hands are made of metal insulating from the remainder of the hand and carrying lugs 87, 90, 94, 97 at their ends and lugs 88, 91, 95, 98 making contact with the strips 67, 70, 68. 69 respectively. When the temperature in the tank 10, and consequently the pressure in the tube 28, rise the hand 42 moves to bring the lugs 87, 96 into contact, thus completing a circuit through the strips 67, 68, the ends 86', 93 of the hands 42, 43, leads 75, 80 and an electromagnet 76, which opens -a valve 20 against the action of a spring and allows fluid under pressure to pass from a tank 16 to the tank 10. When the pressure in the tank 10 has risen sufficiently the hand 43 moves away from the hand 42, breaking the circuit and allowing the valve 20 to close until a further rise of temperature occurs in the tank 10. When the temperature in the tank 10 falls the hand 42 moves to bring the lugs 90, 97 into contact, closing a circuit through the strips 69, 70, ends 89, 96 of the hands 42, 43, leads 83, 86 and an electromagnet 84 which opens a valve 21 allowing the fluid in the tank 10 to exhaust into the air until the pressure has fallen sufficiently to move the hand 43 away from the hand 42.

Abstract: 112,004. Wellen, U. A. H., and Martens, H. T. B. Dec. 8, 1916, [Convention date]. Link-work. - Relates to means for converting the oscillating motion of a ring into the rotary motion of a shaft and vice versa. A shaft 9, 14 to which rotation is to be imparted is supported in ball-bearings 15 fixed in a framing 1 and in ball-bearings 11 in a ring 8. The ring 8 is pivoted on a diametrical axis 8<a> in a gimbal ring 5 supported in bearings 4, 4, or the ring 8 may be otherwise suitably mounted. The axis 8<a> is at rightangles to the axis of the bearings 4, 4, and the axis of the part 14 of the shaft passes through the centre of the ring 8. The shaft 14 is rotated by oscillating the ring 8 or the ring 5 by suitable means such as a cup 17 attached to the ring 8 and having handles 18. An oscillating motion may be imparted to the rings by rotating the shaft 14. Reference has been directed by the Comptroller to Specifications 2377/01, 26546/03, and 5928/13.

Title: Improvements in and relating to locomotive and like exhaust-steam boiler-feed injectors
IPC: B60T13/10
Filed: 1924-07-01
Abstract: 236,830. Friedmann, L., Blauhorn, E., and Deutsch, H. July 1, 1924. Giffard injectors.-In a device employing a live steam nozzle 3 and an exhaust steam nozzle 4 for forcing water fed to a nozzle 5 through a combining cone 6 and delivery cone 8 into a locomotive boiler, the casing is divided into two parts 1, 2 along a plane perpendicular to the axis of the injector and so that one of these parts contains the set of steam cones and the other part the combining and delivery cones. The purpose of this arrangement is to ensure strict axial coincidence between the cones of each set of cones, as it is stated that slight deviations between the axes of the two sets do not seriously affect the satisfactory operation of the injector. By this arrangement, the parts are more readily assembled with accuracy. The water cone 5 may be positioned in either of the casings 1, 2.

Title: Improvements relating to the manufacture of steel
IPC: C21C5/32
Filed: 1959-01-19
Abstract: A process for refining steel by blowing the whole or a major part of the slagforming material in finely divided form into or on to the melt from above in a converter or rotary furnace with an intermediate slagging operation comprises observation of the following conditions: (a) A first phase lasting at least 55% of the total time.  (b) The quantity of free oxygen used in the first phase is at least 55% of the oxygen used in the first and second phases.  (c) The amount of slag-forming material blown per unit volume of oxidizing gas is at the most equal to 80% of the amount in the second phase.
